Tommie of the "Miracle Mets” (4)
I believe the answer is:
agee
'tommie of the miracle mets' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for agee that I've seen before include "In Ayr not straight" , "American writer" , "off the straight at Gleneagles" , "off the straight on Princes Street" .)
